Amine Based Polar Solvent Treatment for Highly Efficient Inverted Polymer Solar Cells |
| 초록 |
To date, various interfacial dipole layers such as self-assembled dipole monolayer (SADM), ionic liquid molecules (ILMs), conjugated polyelectrolyte (CPE), alcohol/water-soluble conjugated polymer, and polar solvent have been exploited to reduce contact barrier between inorganic electrodes and organic semiconductors and promote enhanced carrier transport and extraction. Here, we demonstrate highly efficient inverted polymer solar cells with power conversion efficiencies of 8.69% by simple surface treatment using polar solvent including ethanol amine. The interfacial dipolar polarization, which comes from interactions between ZnO surface and ethanol amine end groups such as amine group and hydroxyl group to make bonds at mono layer, reduces the contact barrier after surface treatment of ethanol amine on ZnO-R layer. This method provides a promising method, and opens new possibilities for not only the organic photovoltaics but also other organic optoelectronic devices. |
